The Pasco super pulley clamp’s 1.7 cm opening will not allow it clamp the end of the Vernier track.
Pasco makes two versions of the Super Pulley: one has a threaded nut on the inside, and one does not. When sold with the clamp (shown), Pasco usually does not include the threaded nut in the pulley.
If the pulleys do have a threaded nut, it can be attached to a Vernier Dynamics track using the Pulley Bracket (B-SPA). This is the most common way to attach a pulley to the end of the track for the purpose of accelerating a cart on a ramp.
